I am nervous about my marriage
There have been a few incidents in the past weeks that have made me nervous but when I confront him he laughs it off. He has been doing some wild parties with his friends. He keeps telling me he wants to enjoy his bachelorhood now but he loves me and that he wants to be with me forever.
It appears that he is committed to you and just wants to enjoy the time left as a bachelor. This man certainly loves you and wants to be faithful to you for the rest of your life. There are many guys who feel once they are married it will be a full stop to all their fun. Your guy belongs to this breed. As long as it is harmless fun, there is no need to worry. At least he is honest and telling you about his bachelor bashes. You are feeling the pre-wedding jitters which is normal. But you are overreacting, just relax and take each day as it comes.
